State of Missouri, have invented new and useful Improvements in Shock-Absorbers, of which the following is a specification.

The inventlon relates to a shock absorber,

and more particularly to the class of vehicle or automobile shock absorbers.

The primary object of the invention is the revision of a device of this character where many and all undue shocks and jars are absorbed thereby incident to the travel of the vehicle or automobile, thereby relieving the same from its body, thus materially increasof said vehicle or automobile and at the same time assuring perfect comfort to the users or occupants thereof.

Another object of the invention is the provision of a shock absorber of this character wherein the construction thereof is novel in form so thatit can be applied to any well known style of vehicle or automobile to withstand varying loads and to relieve and absorb all shocks and jars when the vehicle or automobile is in motion.

A further object of the invention is the provision of a shock absorber of this character easily adjusted and applied to a vehicle or automobile or removed therefrom with despatch.

A still further object of the invention is the provision of a shock absorber. of this character which is simple .in construction, thoroughly reliable and efficient in operation, strong, durable and inexpensive in manufacture.

Other objects will be in part obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter described, and the scope of the application of which will be indicated in the appended claims.

Tn the accompan ing drawings:

Figure 1 is a si e elevation of an automobile showing the shock absorbers constructed in accordance with the invention applied;

Fig. 2 is a rear elevation thereof;

Fig. 3 is a fraentary vertical transverse Specification of Letters latent.

wherein the same can be readily and sectional view showing in edge elevation the shock absorber; I

Fig. 4 is a horizontal transverse sectional view on the line H of Fig. 1;

Fi 5 is a detail side view of the shock absor er;

"Fig. 6 is a sectional view on the line H of Fig. 5;

Fig. 7 is a sectional view on the line 7--7 of Flg. 6.

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

Referring to the drawings in detail, designates generally an automobile which is of any ordinary Well known construction, B each stationary axle thereof and G each side beam of the truck frame of said automobile, which is of the usual well known construction. Detachably connected with each axle formed with a central internally threaded boss 15' and adjustably engaged in these bosses are hanger rods 16 which are also adjustably engaged in internally threaded bosses 17 formed centrally on wheel yokes 18 having passed therethrough stud axles 19 rotatably supporting friction rollers 20 which are formed with convexed peripheries 21 for a purpose presently described. Detachably mounted on each axle B is a perpendicular casting forming a spreader plate 22 which is of substantially double wedge shape, presenting convergent upper and lower beveled edges 23 and 24, respectively, the same being formed with grooves or channels 25 corresponding to the peripheral shape ,of the friction rollers20 so that the latter will engage and travel therein.

Each spreader plate 22 is formed with a notch 25' finished to provide an irregular surface to present biting spurs 26 for gripping engagement with the axle which is seated in 0 ed or otherwise Patented Feb. 13, 191% I Application filed February '3, 1916. Serial Ito. 76,793.

in spaced relation loo I I lower edge is a clip 27 which coacts with the'notch 25' in sa d plate to embrace the v axle By, and'in this manner the plate 22 is clispbsed at opposite v are coiled retractile springs'28 .whiehyservej, to hold the rollers 20 engaged in the grooves in opposite edges-of the fplate 22,-and' also to reslst the spreadingo 16 when subjected to a-load and .toijshoeks: and jars incident to the travel of the-vehicle 1 for absorbings'uch shocks and jars and sus firmly and securely fastened-u on the axle to prevent-the turning of the p a'te; thereon.

Connected with the wheelyoke 18and sides of the plate 22.

taining the load-of the automobile. 1

"Mounted in the upper end of: thegplate 22 is a resilient block 29 which forms a cushion to be engaged by the side beam C' of the truck frame whenexcess'ive load is carried by the automobile; while formed on opposite sides of the plate 22 are u per . Y and lower arcuate shaped flanges 30 an 31, the same supporting resilient strlps 32 whlch serve as buifers'for the'spring 28 on the excessive extending or contracting ofthe. shock absorber under the influence of shocksand jars andfwhen the springs engagewith s. 32 thetension thereof is l the resilient stri increased upon t e rollers 20 so as to materially resist the spreading action of the rod 16 suspending the said rollers.

It is of course understood that these shock absorbers'are used in conjunction with the springs ordinarily em loyedon automobiles connectlon with .connection ',wi-th,;..the si and serve to absorb al shocks and jars incident to the travel of the automobile, therebyrelieving the. strains upon 'the' body of the same and thus increasing the life of the automobile. v

Each bolt 13 and stud axle 19 has mounted thereonan oil cap 33 adapted to contain oil which is delivered therefrom through a passa e 34 so as to lubricate the sleeve 14 and t erollers 20 respectively.

From the foregoing description, taken in the accompanying drawings, the construction and'operation of my improved shock absorber will be readil apparent and, therefore a more extende explanation has been omitted.

Having'thus described my invention,

claim:

1. A shock absorber comprising a pair of swinging members ada ted for detachable beam f.v a truck carried, by the swingin' the hanger rods F frame, a spreader element adapted to be connected to theaxle of the truck frame, rollers 'members and engageable with the sprea er element, resilient meansfeonnected with the swinging members to hold. therollers in positive engagement with the s reader element and also for tensioningz' t 9; said swinging members, and

buffers arranged on the spreader element in the path of movement of the resilient means .to increase the .tension thereof when en-,

g aged thereby.

. 2, A shock absorber comprising a pair of swinging' members ada te for detachable connection with the si e beam of a truck curely fastening the spreader element on the axles.

shock absorber comprising a pair of swmging' members ada ted for detachable connection with the si e beam of a truck frame, a spreader element adapted to be connected to the axle of the truck frame,

rollers carried by the swinging members and engageable with the spreader element, resilient] means connected with the swinging members to hold the rollers in positive engagement with the spreader element and also for tensioning the said swingin members, bufiers arranged on the sprea er element in the path 0 movement of the resilient means to increase the tension thereof when engaged thereby, means for securely fastening the spreader element on the axles, convergent upper and lower beveled edges on the sprea er element and having channels, and convexed peripheries formed on the rollers correspondin to the channels.

In testimony whereof l aflix my signature in presence oftwo witnesses.
